There is no way anyone at our club wants to dick Barcelona about playing hardball, from khaldoon right down to pep, for different reasons. I have no doubt they would be prepared to pay for this to happen, rather than making it a battle and a legal and media mud slinging. Alternatively they can stay out of it and let it unfold between messi and barca, but i think theyd happily step in with money to avoid any negativity.
But no way are they going to bend over and stick their bums out either, or pay over the top for someone they Could get for free with a bit of bravado.
So to me it is all on Barcelona, how cheeky and stubborn they want to be. If they go down the 150m or various top players route, then itl push messi and us to stick with pushing the clause. if they go reasonable, say garcia and 50m, maybe even Angelino (still 100m's worth that), then it could happen quickly and painless for everyone.
